Summary. A depth-integrated hydrodynamical model of the Ligurian Sea has shown the existence of a seiche motion of the basin with a 5.8 hr period. This result was obtained by using an open model boundary from Nice, France to Calvi, Corsica and an artificial solid boundary from Corsica to Elba and the Italian mainland. This seiche has been identified with a 5.8 hr period wave which was revealed in the sea-level variations at Genoa and Imperia. 相似文献

Two mathematical models of surface gravity wave refraction were applied to a coastal area of the northern Ligurian Sea. A series of refraction patterns was computed by means of wave data recorded at a moored platform operating 1.5 miles off the harbour of Genoa. The numerical calculations provided an effect of wave energy concentration near Chiavari and Lavagna where coastal structures and beaches are often damaged during storm surges. 相似文献

Climate change is a serious threat to all nations. This raises the question of why continuous treaty negotiations for more than two decades have failed to create a viable or adequate international climate regime. The current strategy of addressing climate change misdiagnoses the issue as a pollution problem by focusing on symptoms (emissions) and not on underlying causes (unsustainable development). In short, the wrong treaty is being negotiated. Drawing on negotiation analysis, it is argued that the existing and proposed climate treaties fail to meet the national interests of any party. An alternative strategy for addressing climate change is proposed that reframes the overall approach to reflect all countries’ development needs and links climate protection goals to the development structure of the treaty. The current deadlock over emissions reductions might be overcome and a mutual gains agreement reached by directing international cooperation towards promoting the provision of clean energy services for development and ensuring universal access to those services as part of an ‘early action’ agenda that will complement efforts to utilize forests and reduce other GHGs from multiple sectors. 相似文献

A theoretical model is proposed to describe the evolution of damage in brittle materials, such as concrete and masonry, subjected to increasing or sustained stresses of relatively high intensity. The model is based on the introduction of suitable damage variables in a rheological model. In this way, it is possible to describe the material behaviour under stresses either increasing or constant in time. The capabilities of the model in describing the mechanical response of material elements subjected to different stress histories are illustrated. Some correlations with experimental data from tests performed on masonry and concrete specimens are presented, to assess the reliability of the theoretical predictions. The results of some numerical applications to non‐proportional stress paths are also illustrated. Finally, the limitations of the proposal are discussed and possible further improvements are envisaged. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Landslide risk perception: a case study in Southern Italy 总被引:2,自引:0,他引:2

Perceptions of risk are a key issue when seeking to develop systems, practices and policies to protect local populations. This is particularly evident when risk mitigation strategies involve non-structural measures such as relocation and warning systems which presuppose the active involvement of the communities in question. This study adopts an interdisciplinary approach to studying the perceptions, knowledge and opinions on landslide risk amongst residents in Sarno, a small town in Southern Italy which was hit by disastrous landslides on 5–6 May 1998. The paper presents the results of a survey conducted in the months of March, April and May 2013 using a purpose-designed questionnaire. The survey was conducted using face-to-face interviews with 100 residents, 60 of whom live inside the so-called “red zone”, a territory declared at high residual risk soon after the events of 1998. The questionnaire included questions relating to perceived risk exposure, trust in institutions responsible for risk management, evaluations of risk mitigation measures and the early-warning strategy. The results of the study clearly emerges, amongst other issues, that the organisms which are responsible for risk management in Sarno need to develop more effective communication strategies in order to transmit knowledge about the actions implemented to reduce landslide risk in the area. 相似文献
